100以内的整数四则运算测试程序设计

答题时候输入整数
舍点小数部分。
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
void main()
{
int i;long answer1[10],answer[10];float a[10]; char c[2],str[10];
void anser(float a[],char str[],long answer[]);
void show(long answer[]);
void answer2(long answer1[]);
int score(long answer[],long answer1[]);
do
{
printf("1 : show question\n");
printf("2 : answer the question\n");
printf("3 : show score\n");
printf("4 : show answer\n");
printf("5 : exit\n");
scanf("%d",&i);
switch(i)
{
case 1:anser(a,str,answer);break;
case 2:answer2(answer1);break;
case 3:printf("your socre is %d\n",score(answer,answer1));break;
case 4:show(answer);break;
case 5:break;
default:printf("bad input\n");
}
}while(i!=5);
